From the Search Engine Strategies in New York there are perhaps 50 pages blogged already by SE Roundtable, Matt Cutts and many more. From what I have read so far the most interesting is the presentation by Randfish on the Search Engine Algorithms.
The powerpoint presentation can be seen here.
One of the things he covered was the Search Engine Ranking Factors which is an excellent piece of reading.
At the end of the session, the attendees got a copy of a SEO CheatSheet (you need to zoom) which is yet another useful piece for SEOs.
I wished I was there, but ok. Next year perhaps.
